Claude Joni/kl Patented Jan. 31, 1933 UNITED STATES PATENT OFFICE CLAUDE DORNIER, OF FRIEDRICHSHAFEN-ON-THE-BODENSEE, GERMANY, ASSIGNOR OF ONE-HALF TO DORNIER-METALLBAUTEN G. M. B. 3., OF FBIEDRICHSHAFEN-ON- THE-BODENSEE, GERMANY Application filed May 6, 1931, Serial No.

My invention relates to the storing of fuel, oil and other liquids in aircraft, and more particularly in the floats of hydroplanes.

It is an object of my invention to improve the storage of such liquids in aircraft and more especially in the floats. To this end I store the liquids in containers having flexible walls deformable under the pressure of the liquid therein, consisting for instance of liquid-tight fabric, cellulosic material, thin sheet metal or the like.

If desired, the containers may be embedded in resilient material which may also be inserted between the containers themselves and the walls of the float or other structure supporting them.

In the drawing afiixed to this specification and forming part several embodiments of my invention are illustrated diagrammatically by way of example.

In the drawing Fig. 1 is an elevation of a deformable "container according to my invention accommodated between rigid walls, while Fig. 2 shows the same tank unsupported save at the bottom,

Fig. 3 is a cross section of an aircraft float with a single container, and

'Fig. 4 is a similar view of a float with three deformable containers accommodated there- Fig. 5 is a similar view showing elastic material arranged between the containers themselves and between these and the walls of the float.

Referring to the drawin and first to F1gs. 1 and 2, dis a container, lled with a llquid, formed of a flexible or deformable material,

112 is the bottom of a float, or other closed-in y the space, on which the container is supported, and b b are side walls of the float or the like. Fig. 2 shows the deformation of the container, when unsupported, under the weight of the liquid.

In Fig. 3 a sin le deformable container d is inserted in a float c, the container walls bein applied against the walls and bottom of oat.

In Fig. 4, f, g, h are three deformable containers accommodated in a float e, the inner 535,314, and in Germany July 26, 1939.

walls of the two outer containers being applied' against the two walls of the central container, the other walls adapting themselves to the section of the float.

In Fig. 5 i is a float braced on the inside by lattice-work frames which do not present flat wall surfaces to t c three containers in, l and m, so that a lining 0 has to be inserted at the bottom and at the side walls of the float for the reception of the containers, similar liners p being inserted between the containers themselves, the elastic liners 0 and 1) distribute the pressure 'of the liquid and transmit it to the structure of the float i and to the containers themselves.

The term float as used in this specification and inthe claims appended thereto is intended to include every kind of floating body connected with aircraft, such as for instance the hulls of flying boats.

a I wish it to be understood that I do not desire to be limited to the exact details of construction shown and described for obvious modifications will occur to a person skilled in the art.

In the claim aflixed to this specification no selection of any particular modification of the invention is intended to the exclusion ofother modifications thereof and the right to subsequentl make claim to any modification not covered by this claim is expressly reserved.

I claim:
